New Mexico charges a weight-distance tax on heavy trucks — whether you live there or just pass through. We handle your WDT registration, quarterly filings, and renewals so you never get stopped at a New Mexico port of entry.
The New Mexico Weight Distance Tax (WDT) permit is required for trucks with a registered gross weight over 26,000 lbs operating on New Mexico highways. New Mexico is unique in taxing based on vehicle weight and miles traveled within the state.
Who Must Register?
Any carrier operating a qualified vehicle — regardless of whether it is based in New Mexico — must register for the WDT before entering the state. This applies to owner-operators and fleets running through New Mexico on interstate routes.
Tax Calculated per Mile.
The WDT rate is based on the vehicle's declared gross weight category and the number of miles driven within New Mexico. Heavier vehicles pay higher per-mile rates. We calculate your liability accurately each quarter.
Permits Issued per Vehicle.
Each qualifying vehicle must have its own NM WDT permit on file before entering New Mexico. We register individual units or entire fleets, ensuring every truck in your operation has valid New Mexico credentials.
Quarterly Reporting.
WDT returns are filed quarterly with the New Mexico Taxation and Revenue Department. Mileage driven in New Mexico during each quarter must be reported accurately. We manage the filing calendar and submit on your behalf.
Fines for Non-Compliance.
Entering New Mexico without a valid WDT permit can result in on-the-spot fines, back taxes, and potential vehicle detainment at ports of entry. Get registered before your first trip through the state.
